There are two claimants for the person who originated the differential gear as applied to roving frames: one is J.Green, a tinsmith of Mansfield, in his patent of 1823; the other is Arnold, who had applied it in America and patented it in early 1823. This latter was the source for Houldsworth's patent in 1826. It seems that Arnold's gearing was secretly communicated to Houldsworth by Charles Richmond, possibly when Houldsworth visited the United States in 1822–3, but more probably in 1825 when Richmond went to England. In return, Richmond received information about parts of a cylinder printing machine from Houldsworth. In the working of the roving frame, as the rovings were wound onto their bobbins and the diameter of the bobbins increased, the bobbin speed had to be reduced to keep the winding on at the same speed while the flyers and drawing rollers had to maintain their initial speed. Although this could be achieved by moving the driving belt along coned pulleys, this method did not provide enough power and slippage occurred. The differential gear combined the direct drive from the main shaft of the roving frame with that from the cone drive, so that only the latter provided the dif-ference between flyer and bobbin speeds, i.e. the winding speeds, thus taking away most of the power from that belt. Henry Houldsworth Senior (1774–1853) was living in Manchester when his son Henry was born, but by 1800 had moved to Glasgow. He built several mills, including a massive one at Anderston, Scotland, in which a Boulton \& Watt steam engine was installed. Henry Houldsworth Junior was probably back in Manchester by 1826, where he was to become an influential cotton spinner as chief partner in his mills, which he moved out to Reddish in 1863–5. He was also a prominent landowner in Cheetham. When William Fairbairn was considering establishing the Association for the Prevention of Steam Boiler Explosions in 1854, he wanted to find an influential manufacturer and mill-owner and he made a happy choice when he turned to Henry Houldsworth for assistance.

Vignoles, who was of Huguenot descent, was orphaned in infancy and brought up in the family of his grandfather, Dr Charles Hutton FRS, Professor of Mathematics at the Royal Military Academy, Woolwich. After service in the Army he travelled to America, arriving in South Carolina in 1817. He was appointed Assistant to the state's Civil Engineer and surveyed much of South Carolina and subsequently Florida. After his return to England in 1823 he established himself as a civil engineer in London, and obtained work from the brothers George and John Rennie.

In 1825 the promoters of the Liverpool \& Manchester Railway (L \& MR) lost their application for an Act of Parliament, discharged their engineer George Stephenson and appointed the Rennie brothers in his place. They in turn employed Vignoles to resurvey the railway, taking a route that would minimize objections. With Vignoles's route, the company obtained its Act in 1826 and appointed Vignoles to supervise the start of construction. After Stephenson was reappointed Chief Engineer, however, he and Vignoles proved incompatible, with the result that Vignoles left the L \& MR early in 1827.

Nevertheless, Vignoles did not sever all connection with the L \& MR. He supported John Braithwaite and John Ericsson in the construction of the locomotive Novelty and was present when it competed in the Rainhill Trials in 1829. He attended the opening of the L \& MR in 1830 and was appointed Engineer to two railways which connected with it, the St Helens \& Runcorn Gap and the Wigan Branch (later extended to Preston as the North Union); he supervised the construction of these.

After the death of the Engineer to the Dublin \& Kingstown Railway, Vignoles supervised construction: the railway, the first in Ireland, was opened in 1834. He was subsequently employed in surveying and constructing many railways in the British Isles and on the European continent; these included the Eastern Counties, the Midland Counties, the Sheffield, Ashton-under-Lyme \& Manchester (which proved for him a financial disaster from which he took many years to recover), and the Waterford \& Limerick. He probably discussed rail of flat-bottom section with R.L. Stevens during the winter of 1830–1 and brought it into use in the UK for the first time in 1836 on the London \& Croydon Railway: subsequently rail of this section became known as "Vignoles rail". He considered that a broader gauge than 4 ft 8½ in. (1.44 m) was desirable for railways, although most of those he built were to this gauge so that they might connect with others. He supported the atmospheric system of propulsion during the 1840s and was instrumental in its early installation on the Dublin \& Kingstown Railway's Dalkey extension. Between 1847 and 1853 he designed and built the noted multi-span suspension bridge at Kiev, Russia, over the River Dnieper, which is more than half a mile (800 m) wide at that point.

Between 1857 and 1863 he surveyed and then supervised the construction of the 155- mile (250 km) Tudela \& Bilbao Railway, which crosses the Cantabrian Pyrenees at an altitude of 2,163 ft (659 m) above sea level. Vignoles outlived his most famous contemporaries to become the grand old man of his profession.

Richard Roberts was the son of a shoemaker and tollkeeper and received only an elementary education at the village school. At the age of 10 his interest in mechanics was stimulated when he was allowed by the Curate, the Revd Griffith Howell, to use his lathe and other tools. As a young man Roberts acquired a considerable local reputation for his mechanical skills, but these were exercised only in his spare time. For many years he worked in the local limestone quarries, until at the age of 20 he obtained employment as a pattern-maker in Staffordshire. In the next few years he worked as a mechanic in Liverpool, Manchester and Salford before moving in 1814 to London, where he obtained employment with Henry Maudslay. In 1816 he set up on his own account in Manchester. He soon established a reputation there for gear-cutting and other general engineering work, especially for the textile industry, and by 1821 he was employing about twelve men. He built machine tools mainly for his own use, including, in 1817, one of the first planing machines.

One of his first inventions was a gas meter, but his first patent was obtained in 1822 for improvements in looms. His most important contribution to textile technology was his invention of the self-acting spinning mule, patented in 1825. The normal fourteen-year term of this patent was extended in 1839 by a further seven years. Between 1826 and 1828 Roberts paid several visits to Alsace, France, arranging cottonspinning machinery for a new factory at Mulhouse. By 1826 he had become a partner in the firm of Sharp Brothers, the company then becoming Sharp, Roberts \& Co. The firm continued to build textile machinery, and in the 1830s it built locomotive engines for the newly created railways and made one experimental steam-carriage for use on roads. The partnership was dissolved in 1843, the Sharps establishing a new works to continue locomotive building while Roberts retained the existing factory, known as the Globe Works, where he soon after took as partners R.G.Dobinson and Benjamin Fothergill (1802–79). This partnership was dissolved c. 1851, and Roberts continued in business on his own for a few years before moving to London as a consulting engineer.

During the 1840s and 1850s Roberts produced many new inventions in a variety of fields, including machine tools, clocks and watches, textile machinery, pumps and ships. One of these was a machine controlled by a punched-card system similar to the Jacquard loom for punching rivet holes in plates. This was used in the construction of the Conway and Menai Straits tubular bridges. Roberts was granted twenty-six patents, many of which, before the Patent Law Amendment Act of 1852, covered more than one invention; there were still other inventions he did not patent. He made his contribution to the discussion which led up to the 1852 Act by publishing, in 1830 and 1833, pamphlets suggesting reform of the Patent Law.

In the early 1820s Roberts helped to establish the Manchester Mechanics' Institute, and in 1823 he was elected a member of the Literary and Philosophical Society of Manchester. He frequently contributed to their proceedings and in 1861 he was made an Honorary Member. He was elected a Member of the Institution of Civil Engineers in 1838. From 1838 to 1843 he served as a councillor of the then-new Municipal Borough of Manchester. In his final years, without the assistance of business partners, Roberts suffered financial difficulties, and at the time of his death a fund for his aid was being raised.

Isaac Holden's father, who had the same name, had been a farmer and lead miner at Alston in Cumbria before moving to work in a coal-mine near Glasgow. After a short period at Kilbarchan grammar school, the younger Isaac was engaged first as a drawboy to two weavers and then, after the family had moved to Johnstone, Scotland, worked in a cotton-spinning mill while attending night school to improve his education. He was able to learn Latin and bookkeeping, but when he was about 15 he was apprenticed to an uncle as a shawl-weaver. This proved to be too much for his strength so he returned to scholastic studies and became Assistant to an able teacher, John Kennedy, who lectured on physics, chemistry and history, which he also taught to his colleague. The elder Isaac died in 1826 and the younger had to provide for his mother and younger brother, but in 1828, at the age of 21, he moved to a teaching post in Leeds. He filled similar positions in Huddersfield and Reading, where in October 1829 he invented and demonstrated the lucifer match but did not seek to exploit it. In 1830 he returned because of ill health to his mother in Scotland, where he began to teach again. However, he was recommended as a bookkeeper to William Townend, member of the firm of Townend Brothers, Cullingworth, near Bingley, Yorkshire. Holden moved there in November 1830 and was soon involved in running the mill, eventually becoming a partner.

In 1833 Holden urged Messrs Townend to introduce seven wool-combing machines of Collier's designs, but they were found to be very imperfect and brought only trouble and loss. In 1836 Holden began experimenting on the machines until they showed reasonable success. He decided to concentrate entirely on developing the combing machine and in 1846 moved to Bradford to form an alliance with Samuel Lister. A joint patent in 1847 covered improvements to the Collier combing machine. The "square motion" imitated the action of the hand-comber more closely and was patented in 1856. Five more patents followed in 1857 and others from 1858 to 1862. Holden recommended that the machines should be introduced into France, where they would be more valuable for the merino trade. This venture was begun in 1848 in the joint partnership of Lister \& Holden, with equal shares of profits. Holden established a mill at Saint-Denis, first with Donisthorpe machines and then with his own "square motion" type. Other mills were founded at Rheims and at Croix, near Roubaix. In 1858 Lister decided to retire from the French concerns and sold his share to Holden. Soon after this, Holden decided to remodel all their machinery for washing and carding the gill machines as well as perfecting the square comb. Four years of excessive application followed, during which time £20,000 was spent in experiments in a small mill at Bradford. The result fully justified the expenditure and the Alston Works was built in Bradford.

Holden was a Liberal and from 1865 to 1868 he represented Knaresborough in Parliament. Later he became the Member of Parliament for the Northern Division of the Riding, Yorkshire, and then for the town of Keighley after the constituencies had been altered. He was liberal in his support of religious, charitable and political objectives. His house at Oakworth, near Keighley, must have been one of the earliest to have been lit by electricity.

(Simón) Bolívar (Simon) Bolivar

The greatest of the leaders of Latin America's struggle for independence from Spain, Simon Bolivar was born in Caracas, Venezuela on 24 July 1783. From an early age he was an advocate of independence from Spain, and he propagandized for it on his travels through Latin America, Europe and the United States. Venezuela declared itself independent in 1811 at his prompting, and in 1813 he led a victorious army into Caracas, gaining for himself the title of “Libertador” (“Liberator”). In 1819 he founded the state of Gran Colombia (including modern-day Venezuela, Colombia, Panama and Ecuador), and became its first president. His only rival of equivalent stature was José de San Martin, who freed his native Argentina and helped in the liberation of Chile and Peru. After Bolivar met San Martin in 1822, the Argentinian resigned his position as protector of Peru and went into exile in France. Bolivar's subsequent victory at the battle of Ayacucho in 1824 finally secured independence for Peru and brought an end to Spanish rule in South America. In 1826 he opened the Congress of Panama, which sought to give concrete form to his ideal of a united confederation of Latin American states – an ideal which has been cherished by many Latin Americans since his day. Disillusioned by the failure of his pan-American ideal in practice, he retired from public life in 1830 and died on 17 December of the same year.
